Effectiveness of zinc supplementation to full term normal infants: a community based double blind, randomized, controlled, clinical trial.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

Body mass index (BMI) was calculated from maternal weight and height that were collected one month after delivery.

Infants' weight, and length, head, chest and mid upper arm circumferences and skin fold thicknesses at triceps, biceps and subscapular area were collected at baseline (before randomization) and once in three months up till 24 months.

Who Took Part

According to the abstract, 78 children were involved.

The age groups tagged for this paper are infants, young children and young adults, both men and women.

How the Study Was Run

The design is described as randomized, double-blind and placebo-controlled.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

A placebo (an inactive look-alike) gave the Vitamin D, K2, Magnesium and Zinc group a baseline to be compared against.

Three hundred and twenty four infants were randomized and allocated to zinc (163) or placebo (161) groups respectively.
